Polymers and composite materials / Advanced materials / Basic and process materials Sub-industry and Supply-chain Study

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 35 records (19.1% of this 183-record cohort). The remaining cohort contains 148 records. The comparison concerns archive composition.

The recorded industry label Advanced materials accounts for 99.5% here (182/183), compared with 93.3% in the parent set (2,664/2,854), an absolute gap of 6.1 percentage points.

74/183 companies link to pages with existing source-supported excerpts (40.4% of the cohort). The other 109 records remain usable for archive composition, but do not support new operating case studies.

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.

The parent set, Advanced materials / Basic and process materials, contains 2,854 records. This cohort contributes 183 (6.4%); 2,671 records remain after excluding it.

The parent set, Polymers and composite materials, contains 185 records. This cohort contributes 183 (98.9%); 2 records remain after excluding it.

Ratio of label participation, not market share; multi-label counts overlap.

Excluding this cohort, the recorded industry label Advanced materials covers 2,482/2,671 remaining records (92.9%), an absolute gap of 6.5 percentage points from this cohort.

The full reporting jurisdiction distribution has 28 labels; the top 3 contain 78/183 records (42.6%).Other known labels contain 105 records.

For 183 records with known labels, the effective category count is 11.7, versus 28 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 18 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Jiangsu × Advanced materials, contains 34 records, or 97.1% of the 35 records carrying the Jiangsu label.

A cell contains company IDs carrying both labels. It does not establish procurement, supply or investment relationships between firms. Multi-label cells may overlap.

This page displays 8 of the full cross-tab’s 29 non-empty cells; the other 21 remain in the analysis.

Non-empty fields are not necessarily accurate or supported by originals.

Counts concern existing reviewed bilingual excerpts, not re-certification of originals or entire reports.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

31 of this cohort’s 183 records link through existing company-ID mappings to 2026 lists from all jurisdictions (16.9%). This intersection measures list linkage, not successful recognition or company growth.

List rows and company IDs are separate counts, not new firms or final recognition.
